Construction companies and builders use approved testers to certify that buildings meet the standards set out in the regulations. Leema Technologies Limited provide building air permeability testing to the required ATTMA TS1 standard and are approved by the British Institute of Non-Destructive Testing. They also provide their testing services for commercial buildings and private home owners who want to conserve the fuel and power use of buildings.

You can find out more about air permeability testing (sometime referred to as ‘air tightness’ or ‘air leakage’) on this page of the Leema Technologies site.
